Creepy stories

"John here?"

My boyfriend came home early (unexpected) from work and I was in the shower. I hear someone come inside our apartment so I said "Hello?"and heard nothing back. A couple minutes later I heard the bathroom door open and an unfamilair voice say "John here?" My stomach went into my throat and I said "No... Who is this?" He says "GOOD." I've never been so afraid in my life. I opened the curtain, saw his face and I broke down. I know he was just pulling a prank on me but in that moment behind the curtain I was scared shitless. I remember how I felt the blood rush out of my body and how I looked for the nearest weapon only to find a wet bar of soap.
